Assembly Response Callback schema change

It seems that yesterday 2021-03-23 the JSON schema for the callback changed for meta.aspect_ratio from a str to a number. Our webhook was set up to parse it as a string and it is now failing. This is causing a production outage for us.

When was this change made, and is intentional and permanent?

Hello, sorry this has impacted your production. We did indeed implement an update to our API to force a float return value for the aspect_ratio meta field value. If you want to message us on support directly, we can chat about how we can make this up to you.
